On this edition of FOCUS In Sound, we welcome a scientist who explores the way the brain encodes information about the world around us – she combines computational and biological approaches to study the mechanisms behind the transformation of sensory representations. Dr. Maria N. Geffen is an Assistant Professor in the Departments of Otorhinolaryngology: Head and Neck Surgery and Neuroscience at the University of Pennsylvania. In 2008, when she was still at Rockefeller, she received the Burroughs Wellcome Fund Career Award at the Scientific Interface, a $500,000 grant designed to help bridge advanced postdoctoral training and the first three years of faculty service.
